Analytical Hierarchical Process (AHP) Techniques and Geospatial Technologies for Groundwater Potential Zone Mapping

Due to its consistent availability, acceptable natural quality, and ease of direct diversion the underprivileged population, groundwater is a vital source water supply. It can also be transported there more swiftly inexpensively. Exploring potential zones (GWPZs) maps therefore essential, especially in semi-arid environments with insufficient surface supplies. The research area assessed using geographic information system methods remote sensing data. Operational Land Imager 8 data, digital elevation models, soil rainfall dug-out-well data were utilized estimate characteristics that influence recharge zones. Maps lineament density, drainage distribution, topographic-wetness index, land use/land cover, land-surface temperature, slope produced. These overlaid based on analytical hierarchical process weightage prioritization at constituency ratio 0.05. resulting map was divided into very high, moderate, low dimensions these categories are 116005.5 ha, 35822.4 20152 2459 ha 259245 respectively. Accordingly, north-east part study expected have high ground‐water potential. Out 55 operational wells sampled, 72.73 % situated areas category had 10.91% while remained 7.27%, 5.45% 3.64% overall result indicates model approach reliable adopted for characterization GWPZs any semi-arid/ arid environment.
